Why Ethernet come to dominate local-area networking protocols almost completely?

Answer 1

Because it is fast, cheap and easy to install and maintain.

Answer 2

Ethernet (the name commonly used for IEEE 802.3 CSMA/CD) is the dominant cabling and low level data delivery technology used in local area networks (LANs). First developed in the 1970s, it was published as an open standard by DEC, Intel, and Xerox (or DIX), and later described as a formal standard by the IEEE. Following are some Ethernet features:

Ethernet transmits data at up to ten million bits per second (10Mbps). Fast Ethernet supports up to 100Mbps and Gigabit Ethernet supports up to 1000Mbps. Many buildings on the Indiana University campus are wired with Fast Ethernet and the campus backbone is Gigabit Ethernet.

Ethernet supports networks built with twisted-pair (10BaseT), thin and thick coaxial (10Base2 and 10Base5, respectively), and fiber-optic (10BaseF) cabling. Fast Ethernets can be built with twisted-pair (100BaseT) and fiber-optic (100BaseF) cabling. Currently, 10BaseT Ethernets are the most common.

Data is transmitted over the network in discrete packets (frames) which are between 64 and 1518 bytes in length (46 to 1500 bytes of data, plus a mandatory 18 bytes of header and CRC information).

Each device on an Ethernet network operates independently and equally, precluding the need for a central controlling device.

Ethernet supports a wide array of data types, including TCP/IP, AppleTalk, and IPX.

because is symply better

Answer 3

yeah, what he said.
